4 NOTE: Interbond 998 can be applied in a single-coat up to 2mils DFT. When applied as a single coat, a stripe coat is recommended to ensure proper thickness on edges and angles. Per STD item 9-32, stripe coats are not required although additional thickness measurements must be taken to ensure proper thicknesses on edges and angles. Applicators are cautioned as coating thickness increases above 2 mils DFT the risk of runs, drips, and sags increases.

SPECIAL INSTRUCTIONS: N/A IF OVERCOAT WINDOW HAS BEEN EXCEEDED FOR CRITICAL APPLICATIONS: If the overcoat window has been exceeded, Clean surface of coating per SSPC-SP 1, aggressively abrade surface with 8 grit sandpaper or equivalent to promote adhesion, clean surface to SSPC-SP 1 again. ADDITIONAL DATA/INSTRUCTIONS: II. MANUFACTURERS DATA: III. PROPERTIES: IV. SURFACE PREPARATION MINIMUM REQUIREMENTS: Cleaning via UHP-WJ does not create an anchor tooth profile.

8 Dry times are normally a function of humidity, ventilation and temperature. Information given is to be used as a guideline only. When substrate temperatures fall below 5 F after application, the Interbond 998 Primer dry time is retarded requiring additional dry time. Applicators must take this into consideration before the next coating process is started in allowing for sufficient dry time. For crew use Interbond 998 can be overcoated with Interfine 979SG. Application of the Interfine 979SG over the Interbond 998 must occur between thumb print tacky and maximum 24 hours. The technical data given herein has been compiled for your assistance and guidance. It is based upon our experience and knowledge.
